This incredible video comes to us from our friend Tbobborap1, who filmed the giant-scale model at an RC event at the Royal Air Force Barkston Heath base in Grantham, Lincolnshire, England. Our mystery plane is of late WW II vintage, was carrier-based and flew for the United Kingdom, Canada and Australia. It was especially prized as a submarine-hunter. Make your guess in the comments section, then watch the video of this outstanding scale model in flight. Kudos to the builder and pilot, who as of this writing have not been identified.

The Fairey Firefly was a hugely successful WW2 two seat carrier based fighter aircraft that served with the Royal Fleet Air Arm in the latter stages all the way up to the 1950s. The system was a powerful navy fighter capable of attacking aircraft and seagoing vessels alike. It was highly effective on many fronts including the European and Pacific theatres. The single engine round wing cantilever wing monoplane had about 1,700 aircraft made before ending production. The Navy version was made with a tail hook and folding wings for carrier service.

The Fairey Firefly was a British Second World War-era carrier-borne fighter aircraft and anti-submarine aircraft of the Fleet Air Arm (FAA).
It was superior in performance and firepower to its predecessor, the Fulmar, but only entered operational service towards the end of the war. Designed around the contemporary FAA concept of a two-seat fleet reconnaissance/fighter, the pilot and navigator/weapons officer were housed in separate stations. The design proved to be sturdy, long-ranging and docile in carrier operations, although the limitations of a single engine in a heavy airframe reduced overall performance.
The Fairey Firefly served in the Second World War as a fleet fighter but in postwar service, although it was superseded by more modern jet aircraft, the Firefly was adapted to other roles, including strike operations and anti-submarine warfare, remaining a mainstay of the FAA until the mid-1950s. Both the UK and Australia Fireflies flew ground attack operations off various aircraft carriers in the Korean War. In foreign service, the type was in operation with the naval air arms of Australia, Canada, India, and the Netherlands whose Fireflies carried out a few attack sorties as late as 1962 in Dutch New Guinea.

I was remembering that many years ago Dave Platt drew a beautiful 3-view drawing of a later Mk Firefly and commented that it would make an excellent RC warbird because of the generous tail surfaces. I think these were published in MAN, but it may have been RCM.
